Since I'm stuck at home while we go through this COVID-19 crisis, I'm spending time planning my trips back to Asia later this year (assuming everything will be ok by then). It seems like SQ and DL have some sort of partnership. DL's website clearly states that SQ flights earn no miles and won't recognize medallion status. That's fine. However, can I credit the SQ flights to SQ's own program even though the SQ flight is part of a DL-issued ticket?

Thanks!

Delta and Singapore Airlines are definitely not partners. They may interline and sell each other's flights on their tickets so can you transfer without issue, but there is no mileage earning. You can provide your Krisflyer number on your SQ flight to earn miles with them.

I had assumed there was a partnership because DL is selling a ticket with SQ flying one segment. So how do I get my Krisflyer number on the SQ flight? Have you actually done this before?

Get the SQ PNR from Delta (if you ticketed with Delta). Then pull up the itinerary on SQ website to attach your KF FF#. If that doesn't work then call SQ with the PNR.

Note that if the flight number begins with DL (it is marketed as a DL codeshare), it may not earn anything on SQ. I don't know if DL codeshares with SQ or not.

DL and SQ do not codeshare -- https://pro.delta.com/content/agency...-partners.html
Note there is no "partnership" between DL and SQ, they only have an interline agreement allowing the sale of each other's flights on a single ticket. I don't know if this is an issue for KrisFlyer miles, but I believe sometimes airlines may not give credit if flights are not ticketed by itself or a partner.

DL sells some Asian destinations using SQ/ANA for connections. The SQ/ANA flights dont earn any DL miles.

You can have both on file. Since you earn nothing for DL flighrs in SQ/ANA (or vv) program there's no issue if system sends to wrong program.

Issue comes up when you can earn in the other program. In that case system sees you already got credit and denies. (This happens frequently with DL SM and AF/KL/KQs FB program)

Do note some programs care about ticket stock. (DL doesn't) Thus make sure itll earn if on DL ticket stock.

This is what I would try.

If that doesn�t work, have them add/change it at the gate before boarding the SQ flight.

I�ve done that once before with no issue (checked in with UA*G FF# so that I could get into the lounge, then changed back to SQ FF# at the gate due to more favorable earning rate).

Thanks for the response. Have you actually tried this before?

I searched the itinerary again and the flight clearly begins with a SQ. It's the same with NH as well.

I have read about that being possible in the past, but apparently it's no longer possible with UA? I would love to try that if it still works.

Have you tried this before? I don't see any way to add my SQ or NH #s to my DL account. I suspect if this is possible, it'll have to be done on the phone or at the check-in counter.

Of course, many times. Not personally with DL/SQ but that is irrelevant. If you have a SQ flight, you can add an SQ number to that flight through SQ. It's very straightforward. It may be that the SQ fare class doesn't earn points, but if so there's nothing different you can do about that.

I wouldn't bother with trying to add 'two' FF numbers to your itinerary. While some programs can do this, there is absolutely no purpose in your case. Just use your SQ number on the SQ flight and carry on. Don't bother Delta with this, it is not necessary and you'd get no benefits from it.

I have entered SQ lounges by just showing a Star Alliance Gold card before. And left my VA number on the SQ reservation. So at least in my experience there is no need to do a FF shuffle, just show your card.

Not sure why it wouldn't be possible? In the case that I mentioned, it wasn't a UA lounge that I was using, but another *A partner lounge.

It's pretty rare that I find myself in the same scenario (not crediting *A flight to UA), but will try that in future if I find myself in a similar situation. The one time that I did it before was not to get into a SQ lounge, but for another *A carrier lounge. And some of those lounges have automated gates where you scan your boarding pass (some NZ & SK lounges come to mind), so I'd have to call over one of the attendants if my UA*G FF# wasn't on the boarding pass. But not a big deal, I suppose.

Yes I have been denied at a the *A lounge at LAX once, when I had my VA number on an itinerary but only a physical *A Gold card. So it may not work everywhere.

They did take my BP, put the *G number on the reservation, reprinted it, then let me in. So after I got in I called and changed it back to VA. A bit ridiculous, but anyway...

SQ lounges have always been fine with it though.

Thank you. On DL, it's showing as a SQ K-fare. Not sure if it's the same K-fare if bought separately from SQ. If it's the same, it'll be 50%, so I want to get something for it.

I won't bother contacting Delta, but the only way that I can think of to get my SQ # on it would be to call them. Since I only have a layover at ICN, I won't have enough time to add my SQ # at the ticket counter.

As I said in my first post, if you call Delta you can ask them for the SQ PNR. Then you can manage the SQ reservation on the SQ website, using that info. Not sure if you can add your SQ number then, but usually it is possible.

It will also be a lot easier to call SQ, if you already have the SQ PNR
